摘要： A plurality of optical fibers are arranged in parallel and peripheries of the plurality of these optical fibers are integrally formed using a sheath. Here, the sheath is formed over the entire length of optical fiber ribbons and a flat portion of the sheath is formed substantially parallel to a common tangent of the neighboring optical fibers. A maximum value of a thickness of the optical fiber ribbons is set to a value which is larger than an outer diameter of the optical fibers by 40 μm or less. Due to such a constitution, it is possible to easily branch the optical fibers from the integrally formed optical fiber ribbons.

摘要： The present invention provides a PDP especially having a high definition or super high definition cell structure and realizing excellent image display performance by obtaining light-emitting efficiency as favorable as or more favorable than conventional PDPs while suppressing discharge voltage rise.Therefore, strip-shaped display electrodes 4 and 5 of a PDP 1 are respectively composed of a combination of a transparent electrode 41 and a bus electrode 42 and a combination of a transparent electrode 51 and a bus electrode 52. An electrode gap d between electrodes 41 and 51 falls in a range of 5 μm to 60 μm. A ratio of a total surface area of the electrodes 41 and 51 to a total surface area of discharge cells falls in a range of 0.6 to 0.92. Thus, a discharge start length is larger than the electrode gap d. A product of a total pressure P of a discharge gas and the electrode gap d falls in a range of 13.33 Pa·cm to 133.3 Pa·cm. The discharge gas consists of xenon of 100%. The total pressure P of the discharge gas falls in a range of 2.0 kPa to 53.3 kPa. Thus, a start point of discharge is longer than electrode gap d.

摘要： In a method for producing a multilayer printed wiring board, first and second copper foils for surface layer are disposed on both sides of an inner wiring substrate so that each of first and second prepreg sheets provided with through-holes is sandwiched between each of the copper foils for surface layer and each face of the substrate, the through-holes being formed therethrough at desired positions corresponding to positions where the connecting pads on each face of the substrate are formed, and the resulting structure is integrally bonded by applying heat and pressure thereto. During the heat- and pressure-processing step, the through-holes within the prepreg sheets are filled with a resin fused from the prepreg sheets. After selectively removing the copper foil for surface layer within an area which matches each of the connecting pads, the resin is selectively removed by the irradiation of laser beams to form via holes and allow the connecting pads to be exposed. Next, a conductive paste is embedded in the via holes. According to the above-mentioned method, it is possible to suppress occurrence of defective in boring of the via hole for electrically connecting circuit patterns of the surface layer to circuit patterns of the inner layer and also to shorten the production term and reduce the production cost.

摘要： Disclosed is a process for preparing a multi-layer printed wiring board including the step of forming a through hole and an external layer circuit on a laminated board of double-sided or multi-layer construction. Then the laminated board is coated over the whole front and back surfaces with a paste-like heat-resistant resin, simultaneously filling the through hole with a resin. A copper foil is disposed on the whole front and back surfaces of the laminated board. Next, the arrangement is heated and pressure-molded in a vacuum. The copper foil is then removed to form an intermediate laminated board. Then, multilayer molding of at least two sets of intermediate laminated boards with a prepreg interposed therebetween is preformed via a step of heat and pressure-molding. In using the penetrated through hole as the divided via hole, there is no longer a restriction of the thickness of the respective divided via holes on the same lattice point. Thus, it has become possible to use the via holes in a higher multilayer board, dramatically improving wiring capacity over the prior art divided via holes.
